Nonparametric Estimation of the Interval Reliability [PDF]

open access: yesJournal of Statistical Theory and Applications (JSTA), 2014
The interval reliability of a repairable system is the probability that the system is operating at a specified time and will continue to operate for a specified interval of time.

Generalized fiducial inference for normal linear mixed models [PDF]

open access: yes, 2012
While linear mixed modeling methods are foundational concepts introduced in any statistical education, adequate general methods for interval estimation involving models with more than a few variance components are lacking, especially in the unbalanced ...

METHODS OF MEASURING THE EFFECTS OF LIGHTNING BY SIMULATING ITS STRIKES WITH THE INTERVAL ASSESSMENT OF THE RESULTS OF MEASUREMENTS

open access: yesИзвестия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2017
The article presents the results of the development of new methods aimed at more accurate interval estimate of the experimental values of voltages on grounding devices of substations and circuits in the control cables, that occur when lightning strikes ...

Penalized nonparametric mean square estimation of the coefficients of diffusion processes [PDF]

open access: yes, 2007
We consider a one-dimensional diffusion process $(X_t)$ which is observed at $n+1$ discrete times with regular sampling interval $\Delta$. Assuming that $(X_t)$ is strictly stationary, we propose nonparametric estimators of the drift and diffusion ...

Statistical Inferences for Lomax Distribution Based on Record Values (Bayesian and Classical) [PDF]

open access: yes, 2012
A maximum likelihood estimation (MLE) based on records is obtained and a proper prior distribution to attain a Bayes estimation (both informative and non-informative) based on records for quadratic loss and squared error loss functions is also calculated.

Assessing standardized contrast effects in ANCOVA: Confidence intervals, precision evaluations, and sample size requirements.

open access: yesPLoS ONE, 2023
Standardized effect sizes and confidence intervals are useful statistical assessments for comparing results across different studies when measurement units are not directly comparable.

Lasso Estimation of an Interval-Valued Multiple Regression Model

open access: yes, 2015
A multiple interval-valued linear regression model considering all the cross-relationships between the mids and spreads of the intervals has been introduced recently.

Estimation of Gini Index within Pre-Specied Error Bound [PDF]

open access: yes, 2015
Gini index is a widely used measure of economic inequality. This article develops a general theory for constructing a confidence interval for Gini index with a specified confidence coefficient and a specified width.

Overconfidence in Interval Estimates. [PDF]

open access: yesJournal of Experimental Psychology: Learning, Memory, and Cognition, 2004
Judges were asked to make numerical estimates (e.g., "In what year was the first flight of a hot air balloon?"). Judges provided high and low estimates such that they were X% sure that the correct answer lay between them. They exhibited substantial overconfidence: The correct answer fell inside their intervals much less than X% of the time.
